4总结
在目前的热带气旋研究中,海气相互作用的影响受到了越来越多的关注,通过中尺度海气耦合模式研究热带气旋也日益成为热带气旋数值模拟中的热点。当今,对地球物理系统的理解和预报已经超出了单个模式范畴,进入了多模式跨学科的相互作用耦合时代。亿万次计算机系统和高性能网络使对区域中小尺度高分辨率的多模式耦合模拟得以实现。WRF_ROMS-1.2耦合模式就是新一代中尺度耦合模式的典型代表。该模式采用分布式并行计算方式,将大尺度海气耦合模式中常用的耦合器应用于中尺度海气耦合模式,并采用了目前国际上十分流行的ROMS海洋模式,这些亮点都是当前国内诸多基于进程间通讯机制研发的海气耦合模式不能比拟的,值得引进和借鉴。本文简要介绍了WRF_ROMS-1.2模式的耦合方法和结构框架,希望能为多模式耦合系统的建立以及中尺度海气相互作用(尤其是热带气旋期间的海气相互作用)的研究、模拟和预报提供建设性参考。参考文献:
